Jon925mn 39 #1 Posted September 18, 2021 Picked up a C-161 twin auto with this replacement engine. Tag is not readable so unsure what I have here. Single cylinder ohv that was told used on a generator. Any ideas what model/year/hp this is so I can find replacement parts when needed. Like right now oil/air filters and proper plug. Outside of the PP muffler noise this engine is very smooth with no noise or smoke. Share this post Link to post Share on other sites

bds1984 1,435 #3 Posted September 18, 2021 That is a Kohler Command all day long. Judging by the cobbled exhaust and oil filter position compared to the one on my Wheel Horse, I'd be willing to bet a dollar this one didn't come from a Wheel Horse which makes me wonder if it has the proper bearings on the crank to support the manual PTO.

pfrederi 17,741 #4 Posted September 18, 2021 (edited) Usually Generator engines have a short tapered shaft as they are direct coupled. There is an adapter sold on Ebay to makes it a straight shaft. Point is if it had the tapered shaft and was direct coupled to a genny it is very doubtful that it has any thrust bearing. Couple of options, you could switch to an electric PTO or make up an external thrust bearing set up as WH used on some B&S engines they used many years ago. I never understood Kohler's labeling.. Stickers how cheap. At least Techy and B&S used to stamp the model info into the Flywheel shroud. Edited September 18, 2021 by pfrederi 1 Share this post Link to post Share on other sites
Jon925mn 39 #5 Posted September 18, 2021 Guess I don't understand the pto issue as both 48" mower and snowblower work great. Share this post Link to post Share on other sites
bds1984 1,435 #6 Posted September 18, 2021 It is more of an issue of directional force applied to the engine crankshaft than how well an attachment functions. The manual PTO pushes towards the flywheel of the engine to engage the attachment which can observed when you push the PTO lever forward. This requires the usage of bearings (ball bearing and thrust bearings) that can handle the longitudinal load which many Kohler Command engines do not have but all K-Series and Magnum single cylinder engines do. An electric clutch doesn't apply that type of load to the crankshaft/bearings which allows plain bearings to be used; it applies loads to the crankshaft just like the transmission clutch does, aka 90 degrees from the shaft. Unless that engine came from a Wheel Horse or an application that requires longitudinal loads, it may not last long. We just don't want anyone here to ruin a good engine from it being used in the incorrect application. 3 1 Share this post Link to post Share on other sites
pfrederi 17,741 #7 Posted September 18, 2021 Because Manual PTOs push in fairly hard on the end of the crankshaft (longitudinal loading if you will). On most engines the sleeve bearing on the crankshaft have just a tiny lip that handles any crankshaft end play. That small surface cannot take the heavy pressing in of the manual PTO. It will work...for awhile till that lip wears away then engine will suffer major damage. Share this post Link to post Share on other sites
Jon925mn 39 #8 Posted September 18, 2021 Guess I won't know how it was done only that it's been this way for more than 10 years. I know nothing about adding an electric clutch and sounds pricey. Share this post Link to post Share on other sites
